It may be tonight's wine talking, but what about these ideas (I apologise if they've been mentioned elsewhere):
1] When my other team (Derby) relaid the infamous Baseball ground pitch, they offered mementos of the old pitch, as in the photo I hope I've attached (haven't tried this before). I'd certainly buy a sample of the York Street pitch.
2] I have a framed photo of the old Baseball ground (a rather unatmospheric aerial view, unfortunately). I'd love an atmospheric photo of York Street.
and
3] Like the rest of you, I've no idea what's going to happen next season (or even this, at the time of writing). I feel the Chestnuts deserve as much support as people are able to give, and I will buy a season ticket for next year even if I don't see a ball kicked in the flesh.
It probably is the wine, but that's how I feel!
